BACKGROUND 1. Technical Field

The present disclosure relates to a semiconductor device package and a method of manufacturing the same, and more particularly to a semiconductor device package including an emitting component and a method of manufacturing the same.

2. Description of the Related Art

Wireless communication devices, such as cell phones, typically include antennas for transmitting and receiving radio frequency (RF) signals. Comparably, a wireless communication device includes an antenna and a communication module, each disposed on different parts of a circuit board. Under the comparable approach, the antenna and the communication module are separately manufactured and electrically connected together after being placed on the circuit board. Accordingly, separate manufacturing costs may be incurred for both components. Furthermore, it may be difficult to reduce a size of the wireless communication device to attain a suitably compact product design. To reduce the cost and package size, an Antenna-in-Package (AiP) approach is provided. In general, an organic substrate is commonly used in an AiP system. However, due to the process limitation of the organic substrate, it is difficult to achieve fine-pitch (less than 15/15 μm), and the thickness of the organic substrate is relatively thick, which will hinder the miniaturization of the AiP system.

SUMMARY

In accordance with some embodiments of the present disclosure, a semiconductor device package includes a carrier, an emitting element and a first package body. The carrier includes a first surface and a second surface opposite to the first surface. The emitting element is disposed on the first surface of the carrier. The first package body is disposed over the first surface of the carrier and spaced apart from the first surface of the carrier.

In some embodiments, a width (or an area) of the conductive pad 11 p is greater than a width (a diameter or an area) of the conductive structure 12 a (e.g., a conductive pillar). In some embodiments, a width (or an area) of the conductive via 11 v is less than the width (the diameter or the area) of the conductive structure 12 a.

In some embodiments, the dielectric layer 11 d may include pre-impregnated composite fibers (e.g., pre-preg), BPSG, silicon oxide, silicon nitride, silicon oxynitride, USG, any combination of two or more thereof, or the like. Examples of a pre-preg may include, but are not limited to, a multi-layer structure formed by stacking or laminating a number of pre-impregnated materials/sheets.

In some embodiments, the conductive layer 11 c, the conductive pad 11 p and the conductive via are formed of or includes Au, Ag, Cu, Pt, Pd, or an alloy thereof.

One or more conductive structures 12 a (e.g., conductive pillars or conductive elements) are disposed on the surface 111 of the circuit layer 11. The conductive structures 12 a are electrically connected to the circuit layer 11 through the conductive pad 11 p. In some embodiments, the conductive structure 12 a is in contact with the conductive pad 11 p. In some embodiments, the conductive structure 12 a may be connected to the conductive pad 11 p through an adhesive layer or a seed layer. For example, the adhesive layer or the seed layer is in contact with both the conductive structure 12 a and the conductive pad 11 p. In some embodiments, the conductive structures 12 a may define an antenna structure. The conductive structure 12 a is, or includes, a conductive material such as a metal or metal alloy. Examples of the conductive material include Au, Ag, Cu, Pt, Pd, or an alloy thereof.

The package body 18 is disposed on the surface 111 of the circuit layer 11. The package body 18 covers the conductive structures 12 a and the conductive pad 11 p. In some embodiments, the package body 18 has a lateral surface substantially coplanar with the lateral surface 113 of the circuit layer 11.

The electronic component 15 is disposed on the surface of the circuit layer 13 facing away from the circuit layer 11. The electronic component 15 may be an active electronic component, such as an integrated circuit (IC) chip or a die. The active surface of the electronic component 15 faces the circuit layer 13.

In some embodiments, an underfill 15 f is disposed between the electronic component 15 and the circuit layer 13 to cover the electrical contacts 15 s. In other embodiments, the underfill 15 f may be omitted.

FIG. 1B illustrates a cross-sectional view of a semiconductor device package 1B in accordance with some embodiments of the present disclosure. The semiconductor device package 1B is similar to the semiconductor device package 1A as shown in FIG. 1A, except that in FIG. 1B, conductive pad 11 p as shown in FIG. 1A is omitted. The conductive structure 12 a has a portion (e.g., the conductive via 11 v) further extending within the dielectric layer 11 d and electrically connected to the conductive layer 11 c.

FIG. 2 illustrates a cross-sectional view of a semiconductor device package 2 in accordance with some embodiments of the present disclosure. The semiconductor device package 2 is similar to the semiconductor device package 1A as shown in FIG. 1A, and the differences therebetween are described below.

Referring to FIG. 2 , a width (or an area) of a conductive pad 11 p′ is less than the width (or the area) of the conductive structure 12 a. For example, a top surface and a lateral surface of the conductive pad 11 p′ are covered by the conductive structure 12 a. In some embodiments, the top surface and the lateral surface of the conductive pad 11 p′ are in contact with the conductive structure 12 a. In some embodiments, the width (or the area) of a conductive pad 11 p′ may be equal to the width (or the area) of the conductive via 11 v. Alternatively, the width (or the area) of a conductive pad 11 p′ may be greater than or less than the width (or the area) of the conductive via 11 v.

FIG. 3 illustrates a cross-sectional view of a semiconductor device package 3 in accordance with some embodiments of the present disclosure.

The package body 17 is in contact with the dielectric layer 10 d 1 and the conductive layer 10 p.

FIG. 5A, FIG. 5B, FIG. 5C, FIG. 5D, FIG. 5E, FIG. 5F, FIG. 5G and FIG. 5H illustrate a semiconductor manufacturing method in accordance with some embodiments of the present disclosure. In some embodiments, the method in FIG. 5A, FIG. 5B, FIG. 5C, FIG. 5D, FIG. 5E, FIG. 5F, FIG. 5G and FIG. 5H can be used to manufacture the semiconductor device package 1B in FIG. 1B.

Referring to FIG. 5A, a carrier 10 is provided. The carrier 10 may be in a wafer type, a panel type or a strip type. In some embodiments, the carrier 10 may be a glass wafer. A circuit layer 11 including one or more conductive layers 11 c and one or more dielectric layers 11 d is formed on a surface 101 of the carrier 10. The dielectric layer 11 d may be formed by, for example but is not limited to, photolithographic technique. One or more holes 11 h are formed to penetrate a portion of the dielectric layer 11 d and to expose a portion of the conductive layer 11 c.

Referring to FIG. 5B, a carrier 59 having an adhesive layer 59 h (e.g., a tape or glue) is disposed on the circuit layer 11. The adhesive layer 59 h is disposed on the dielectric layer 11 d and may extend within the holes 11 h. In some embodiments, a seed layer may be disposed between the adhesive layer 59 h and the dielectric layer 11 d.

Referring to FIG. 5C, a portion of the carrier 10 and a portion of the carrier 59 are removed to reduce the thickness of each of the carrier 10 and the carrier 59. In some embodiments, the carrier 10 and the carrier 59 may be thinned by, for example, grinding or any other suitable processes. In some embodiments, each of the carrier 10 and the carrier 59 may have a thickness more than 400 micrometers before the thinning operation as shown in FIG. 5C. For example, each of the carrier 10 and the carrier 59 may have the thickness about 700 micrometers. In some embodiments, after the thinning operation as shown in FIG. 5C, the thickness of each of the carrier 10 and the carrier 59 is about 400 micrometers. Each of the carrier 10 and the carrier 59 may have any thicknesses depending on different design specifications.

Referring to FIG. 5D, a dielectric layer 10 d 1 is formed on a surface 102 of the carrier 10. Conductive layers 10 p are formed on the dielectric layer 10 d 1. In some embodiments, the conductive layers 10 p may be antenna patterns, light emitting devices or sensors. A dielectric layer 10 d 2 is then formed on the dielectric layer 10 d 1 to cover the conductive layers 10 p. In some embodiments, the dielectric layer 10 d 1 may be omitted, and the conductive layers 10 p are directly formed on the surface 102 of the carrier 10.

Referring to FIG. 5E, a package body 17 is formed on the dielectric layer 10 d 2. In some embodiments, the package body 17 is formed by, for example, by a transfer molding technique, a compression technique or any other suitable techniques. In some embodiments, the dielectric layer 10 d 2 may be omitted, and the package body 17 is directly formed on the dielectric layer 10 d 1 and covers the conductive layers 10 p.

Referring to FIG. 5F, the carrier 59 and the adhesive layer 59 h are removed from the dielectric layer 11 d to expose the holes 11 h and a surface of the dielectric layer 11 d facing away from the carrier 10.

Referring to FIG. 5G, conductive structures 12 a are formed on the circuit layer 11 to be electrically connected to the circuit layer 11. For example, the conductive structures 12 a may extend within the holes 11 h and connected to the conductive layer 11 c. In some embodiments, the conductive structures 12 a may be formed by, for example but is not limited to, plating technique.

A package body 18 is then formed on the dielectric layer 11 d to fully cover the conductive structures 12 a. In some embodiments, the package body 18 is formed by, for example, by a transfer molding technique, a compression technique or any other suitable techniques.

Referring to FIG. 5H, a portion of the package body 18 is removed to expose a portion (e.g., a top surface) of the conductive structures 12 a. A circuit layer 13 including one or more conductive layers 13 c and one or more dielectric layers 13 d is formed on the package body 18 and electrically connected to the conductive structures 12 a. For example, the conductive layer 13 c of the circuit layer 13 is electrically connected to the top surface of the conductive structures 12 a exposed from the package body 18.

Conductive structures 12 b are formed on the circuit layer 13 and electrically connected to the circuit layer 13. An electronic component 15 is then disposed on the circuit layer 13 and electrically connected to the circuit layer 13 through electrical contacts 15 s (e.g., solder balls). In some embodiments, the electronic component 15 may be connected to the circuit layer 13 through flip-chip or any other suitable processes. In some embodiments, an underfill 15 f may be formed between the electronic component 15 and the circuit layer 13 to cover the electrical contacts 15 s.

In some embodiments, singulation may be performed to separate out individual semiconductor package devices including the semiconductor package device 1B as shown in FIG. 1B. That is, the singulation is performed through the dielectric layers 10 d 1, 10 d 2, the circuit layers 11, 13 and the package bodies 17, 18. The singulation may be performed, for example, by using a dicing saw, laser or other appropriate cutting technique.

In some comparative embodiments, after the operation illustrated in FIG. 5A, conductive structures 12 a may be directly formed on the circuit layer 11 without placing the carrier 59 on the circuit layer 11. The package body 18 is formed on the circuit layer 11 to cover the conductive structures 12 a. Then the dielectric layers 10 d 1, 10 d 2, the conductive layers 10 p and the package body 17 are formed on the surface 102 of the carrier 10. However, since the carrier 10 has a relatively thin thickness (e.g., 400 micrometers), the rigidity or the structural strength of carrier 10 is insufficient for handling the processes as mentioned above. Hence, a warpage issue will occur for the carrier 10 due to the CTE mismatch between the carrier 10, the dielectric layers 10 d 1, 10 d 2, 11 d and the package bodies 17, 18. In some embodiments, the carrier 10 may have a warpage of about 4 millimeters, which would render the failure of the processes as mentioned above.

In accordance with the embodiments as shown in FIG. 5B, the carrier 59 is disposed on the circuit layer 11. The dielectric layers 10 d 1, 10 d 2, the conductive layer 10 p and the package body 17 are formed on the surface 102 of the carrier 10 as shown in FIGS. 5C to 5E. Since the carrier 59 can be used to balance the stress applied to the structure during the processes and to enhance the structural strength, the warpage issue can be eliminated or mitigated, which would increase the yield of manufacturing the semiconductor device package.

FIG. 6A, FIG. 6B, FIG. 6C, FIG. 6D, FIG. 6E, FIG. 6F, FIG. 6G and FIG. 6H illustrate a semiconductor manufacturing method in accordance with some embodiments of the present disclosure. In some embodiments, the method in FIG. 6A, FIG. 6B, FIG. 6C, FIG. 6D, FIG. 6E, FIG. 6F, FIG. 6G and FIG. 6H can be used to manufacture the semiconductor device package 1A in FIG. 1A. The operations illustrated in FIG. 6A, FIG. 6B, FIG. 6C, FIG. 6D, FIG. 6E, FIG. 6F, FIG. 6G and FIG. 6H are similar to the operations as shown in FIG. 5A, FIG. 5B, FIG. 5C, FIG. 5D, FIG. 5E, FIG. 5F, FIG. 5G and FIG. 5H, and some of the differences therebetween are described below.

Referring to FIG. 6A, conductive pads 11 p are formed on the circuit layer 11 and electrically connected to the conductive layer 11 c of the circuit layer 11 through conductive vias 11 v. For example, the conductive pad 11 p may include a portion (e.g., the conductive via 11 v) extending into the dielectric layer 11 d and electrically connected to the conductive layer 11 c. In some embodiments, the conductive via 11 v is in contact with the conductive layer 11 c. In other embodiments, a seed layer may be disposed between the conductive via 11 v and the conductive layer 11 c. The conductive pads 11 p are disposed on the dielectric layer 11 d of the circuit layer 11. For example, the conductive pads 11 p are exposed from the dielectric layer 11 d of the circuit layer 11.

Referring to FIG. 6B, the adhesive layer 59 h covers the conductive pads 11 p. In some embodiments, a seed layer may be disposed between the adhesive layer 59 h and the conductive pads 59 h and the dielectric layer 11 d. Referring to FIG. 6F, the carrier 59 is removed to expose the conductive pads 11 p. Referring to FIG. 6G, the conductive structures 12 a are formed on the conductive pads 11 p, and the package body 18 is formed to cover the conductive structures 12 a and a portion of the conductive pads 11 p.

As shown in FIG. 5B, the adhesive layer 59 h is extend within the holes 11 h. The carrier 59 and the adhesive layer 59 h are then removed from the dielectric layer 11 d to expose the holes 11 h as shown in FIG. 5F for the formation of the conductive structures 12 a as shown in FIG. 5G. However, the adhesive layer 59 may not fully removed from the holes 11 h, and parts of the adhesive layer 59 h may remain in the holes 11 h. Thus, the conductive structures 12 a may not extend within the holes 11 h to be electrically connected to the conductive layer 11 c, which would cause an open circuit.

In accordance with the embodiments as shown in FIG. 6A, the conductive pads 11 p are disposed on the corresponding holes 11 h and electrically connected to the conductive layer 11 c through the conductive vias 11 v, and thus the adhesive layer 69 h would not extend within the holes 11 h in the operations shown in FIG. 6B. Therefore, the conductive structures 12 a can be electrically connected to the conductive pads 11 p, and the open circuit issue can be solved.

As used herein, the terms “substantially,” “substantial,” “approximately,” and “about” are used to denote and account for small variations. For example, when used in conjunction with a numerical value, the terms can refer to a range of variation of less than or equal to ±10% of that numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. As another example, a thickness of a film or a layer being “substantially uniform” can refer to a standard deviation of less than or equal to ±10% of an average thickness of the film or the layer, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. The term “substantially coplanar” can refer to two surfaces within micrometers of lying along a same plane, such as within 40 within 30 within 20 within 10 or within 1 μm of lying along the same plane. Two surfaces or components can be deemed to be “substantially perpendicular” if an angle therebetween is, for example, 90°±10°, such as ±5°, ±4°, ±3°, ±2°, ±1°, ±0.5°, ±0.1°, or ±0.05°. When used in conjunction with an event or circumstance, the terms “substantially,” “substantial,” “approximately,” and “about” can refer to instances in which the event or circumstance occurs precisely, as well as instances in which the event or circumstance occurs to a close approximation.

As used herein, the singular terms “a,” “an,” and “the” may include plural referents unless the context clearly dictates otherwise. In the description of some embodiments, a component provided “on” or “over” another component can encompass cases where the former component is directly on (e.g., in physical contact with) the latter component, as well as cases where one or more intervening components are located between the former component and the latter component.

As used herein, the terms “conductive,” “electrically conductive” and “electrical conductivity” refer to an ability to transport an electric current. Electrically conductive materials typically indicate those materials that exhibit little or no opposition to the flow of an electric current. One measure of electrical conductivity is Siemens per meter (S/m). Typically, an electrically conductive material is one having a conductivity greater than approximately 10⁴ S/m, such as at least 10⁵ S/m or at least 10⁶ S/m. The electrical conductivity of a material can sometimes vary with temperature. Unless otherwise specified, the electrical conductivity of a material is measured at room temperature.

Additionally, amounts, ratios, and other numerical values are sometimes presented herein in a range format. It can be understood that such range formats are used for convenience and brevity, and should be understood flexibly to include not only numerical values explicitly specified as limits of a range, but also all individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly specified.

While the present disclosure has been described and illustrated with reference to specific embodiments thereof, these descriptions and illustrations do not limit the present disclosure. It can be clearly understood by those skilled in the art that various changes may be made, and equivalent elements may be substituted within the embodiments without departing from the true spirit and scope of the present disclosure as defined by the appended claims. The illustrations may not necessarily be drawn to scale. There may be distinctions between the artistic renditions in the present disclosure and the actual apparatus, due to variables in manufacturing processes and such. There may be other embodiments of the present disclosure which are not specifically illustrated. The specification and drawings are to be regarded as illustrative rather than restrictive.
